Biodiversity

Question 1

Humans and biodiversity

Answer 1

Economic gain means warning signs for lack of biodiversity are being ignored

Industrial revolution and beyond have left us able to fight against nature

Question 2

Waste is effecting

Answer 2

Water - sewage and toxic chemicals find there way into water sources

Land - landfill sights, toxic herbicides and pesticides and buried nuclear waste all pollute land

Air - smoke and gasses are constantly being added to atmosphere, and contributing to global warming and rising co2 levels

Question 3

Peat bogs

Answer 3

Here carbon remains in plants instead of being released into the atmosphere

Destruction of peat bogs results in burning or decay if peat which releases the carbon into the atmosphere as co2 a greenhouse gass

They are destroyed to make more farming space, to use peat as fuel, to sell the peat

Loss of biodiversity

Question 4

Deforestation consequences

Answer 4

Burning of wood increases rate of co2 going into atmosphere

Less photosynthesis taking place means less co2 removed from atmosphere

Destruction of habitats

Chopped down to make room for farming, farming which incudes producing methane eg cows and rice fields

Question 5

Co2

Answer 5

Co2 is removed from atmosphere by plants during photosynthesis

It’s also stored in water and peat bogs

It’s released naturally as a waste product of respiration

Now there’s artificial ways of releasing it to, unblancing the amount taken in and going out

Question 6

Greenhouse effect

Answer 6

Greenhouse gases act as a natural insulating layer in the atmosphere re radiating most of the heat energy reflected off the earth back towards earth

Causes global warming

Question 7

Consequences of global warming

Answer 7

Ice melting leads to rising sea levels and loss of biodiversity

Extreme events like droughts, storms, floods and wildfires happen more often

Sea surface temperatures rising hurting coral reefs and sealife

Ocean becoming more acidic making it harder to create coral reefs

Migration patterns altering

Distribution of species - species travelling away from the equator cause its to hot

Reduction in biodiversity

Question 8

How to maintain biodiversity

Answer 8

Breeding programmes

Protecting endangered and rare species

Giving money to farmers to help

Government targets like reducing deforestation

Recycling
